Talk:EquipCompare
From WoWWiki
Equip Compare In WoW when you shop for items at a merchant and you hover over an item, you get a comparison tooltip showing the "currently equipped" item too. This AddOn adds such a feature everywhere in the game where you can hover over items, such as in your bags, in the loot window or on the reward page of a quest. You also receive comparison tooltips when clicking an item link in the chat box.
The AddOn is enabled by default. To toggle whether it's on or off, simply type /equipcompare. To turn it on, /equipcompare on. To turn it off, /equipcompare off. You can use /eqc instead of /equipcompare. The AddOn remembers the last setting, but it's per account. Type /equipcompare help for usage information.
